Later citizens loyal to Czechoslovakia were incorporated (for example, many members of the sports organisation Sokol or active anti-fascist Germans).
During September the guard fought low-level warfare against local German partisans (Sudetendeutsches Freikorps) and commandos from Germany.
As a result of First Vienna Award Czechoslovakia was forced to give up territory to Poland and Hungary (southern Slovakia and Carpathian Ruthenia).
From January to March 1939 (until Czechoslovakia was dissolved) heavy clashes occurred between Hungarian forces and guard and the army in Ruthenia.
Estimated warfare losses (both guard and the army) from May 1938 to April 1939 are 171 dead, 404 injured, over thousand of soldiers taken prisoner and abducted to Germany proper.
